Belle

React Components with great User Experience.

Website & Documentation: http://nikgraf.github.io/belle/

Getting Started

Belle is available as npm package. Once you have npm you can install Belle in your project folder with:

npm install belle

Import & use Belle Components

We recommend you get started with React first. Once you have a simple application setup you can import any Belle component and use it right away. No stylesheets, font or any other prerequisite needed.

"use strict";

import React, {Component} from 'react';
import {TextInput} from 'belle';

class App extends Component {

  render() {
    return <div>
      <TextInput defaultValue="Update here and see how the input grows …" />
    </div>;
  }
}

React.render(<App/>, document.getElementById('body'));

In addition you can dig through the documentation to learn about how to modify Belle components.

Philosophy

"Great UX starts with a good UI"

With Belle I'm aiming to provide a library that follows a couple well established principles. While some of them might not be consider best practice today We believe they will become some day in the near future.

Easy to use

The most important attribute of any great experience is that there was no hassle to achieve the initial goals.

Consistent Behavior

Every object someone interacts with has it's own little language. This language must be learned by everyone getting in touch with a new set of object. In order to provide a great experience the amount to learn should be reduced to a minimum.

There are two major personalities to target with Belle. One is the developer. For him/her APIs should be provided in a consistent way through all components. The other and more important is the users of the components. Every color, animation or behavior should be aligned with the other components to provide a great experience.

Encapsulate Styles

There is no reason while a style designed one specific element should affect others. In CSS styles are often defined by overwriting previous ones and introducing deeper and deeper nesting. Once nesting is introduced resolution of styles for one specific element is not a trivial task anymore. Due this managing CSS dependencies is hard. It is hard to predict how an application looks like after updating or removing dependency.

That's why with Belle styles should apply to the components themselves in the DOM. By doing so the visual appearance and business logic are combined in location.

Every Interaction is followed up with Feedback

Let people know how their behavior affects the system. It assures them that their input was acknowledged which provides them with a feeling of control over the system.

High Performance

The user should see affects of his actions instantly. Any delay can cause confusion and frustration. While instant certainly is not always possible Belle strives to provide an experience close to instant.

Development

You can install the development environment with

npm install

Note: In case you want to add a peerDependency please make sure it get's removed after running install since peerDependencies should not be in node_modules to make them work properly. React & Underscore are removed in the postinstall script which is defined in package.json.

Whenever you change something in src/ you can compile it during development with

npm start

Run the examples or docs

To run the examples or docs you should run npm install and npm start in the examples/docs folder as well.

Use python -m SimpleHTTPServer 8310 in the examples folder to run it on localhost.

Future Plans

• Add disabled style to TextInput & Button
• Make sure components don't break when rendered by the backend
• Make sure the components work great on Mobile
• Components to add: rating, autocomplete, dateformatter, datepicker, toggle, checkbox, tooltip, popover, menu/dropdown, NumberInput, EmailInput , anchor?, code?

Special Thanks

The implementation of the TextInput component was heavily inspired by implementations of Andrey Popp & Eugene.
